Letters Patent No. 104,466, dated June 21,1870.

" IMPROVEMENT m V'IHERMOMETERSV.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, J orm KENDALL, of New Lebanon, in the county of Columbia and State of New York, have invented a new and useful Improvement in Thermometers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming a part of this specification.

The object of this invention is to render thermometers more convenient audserviceable in dairies, and for many other uses; and It consists in forming the scale-plate in single piece, with flanged edges, in combination with a removable band for protecting the bulb of the thermometer, as

will be hereinafter more fully described.

In the drawing- Figure l-represents a face View of the thermometer complete, constructed according my invention.

Figure 2 is a cross-section of fig. 1, on the line a; m. Figure 3 is a perspective view of the removable baud.

Similarlctters of reference indicate corresponding parts.

A is the scale-plate, to which the thermometer-tube B is attached, in the ordinary manner.

The plate A hasflanges turned on its edges, as seen at G G, fig. 2.

I) is the bulb of the thermometer.

E is the removable band, which is slipped onto the plateA, so as to cover and protect the bulb, as represented.

In using the ordinary thermometer in, the process of cheese and butter-making, to test the temperature of the curd or cream, and for many other purposes, where the instrument is. used for testing substances which adhere to'the tube or scale, it is found extremely dflicult to cleanse the thermometer, especially the common cup around the bulb, of the adhering substance.

In my improved thermometer there is no cup, but there is the band E, which is held by friction on the plate, and readily'removable.

After'the thermometer has been used in the curd,

cream, or other substance, the band is slipped off, which leaves the instrument unobstructed for cleaning.

Being a manufacturer ,of thermometers, I have been induced to make the above improvement with a 'view of obviating objections so frequently made to the thermometers in common use, for the purposes above mentioned.

Having thus described my invention,

' What I claim as new, and desire to secure by Letters Patent, is-.

1. Asa new and improved article of manufacture,

thermometers with the removable band E, substantially as and for the purposes described.

i 2. In combination with the scale Aand band E,the flanges G O, substantially as shown and described.

The above specification of my invention signed by me this 9th day of April, 1870.

JOHN KENDALL.
